如何在 Spring Boot v2.6.2 中使用嵌入式 MongoDB？
How to use embedded MongoDB with SpringBoot v2.6.2?
我正在使用 Spring Boot v2.6.2 和 Java v17 并尝试在没有 MongoDBService 运行ning 的情况下测试我的 MongoConnection 因为它应该是在构建机器上使用嵌入式内存 MongoDB 进行测试，无需在那里设置额外的 MongoDB 服务。
当然，在生产系统上，它应该使用完整的 MongoDB.
我试着得到这个简单的例子 运行ning:
@DataMongoTest
public class MongoTest
{
@Autowired
private UserRepository userRepository;
@AfterEach
void cleanUpDatabase()
{
this.userRepository.deleteAll();
}
@Test
void bootstrapTestDataWithMongoTemplate() {
final var restaurant = new User( "123", "ABC", "DEF" );
this.userRepository.insert( restaurant );
final var found = this.userRepository.findByFirstName( "ABC" );
System.out.println( found );
}
}
UserRepository 是扩展 MongoRepository 的接口。 User 本身只是一个带有 @Document 注释的 DBEntity。如果我让 Spring 启动应用程序 运行，而不是测试模式，一切正常，因为 MongoDB 在指定位置 运行ning。但是为了测试，我想让它运行作为一个内存DB。
但是 Springboot 想要连接以进行测试。

文档指出：
2.2.4. Embedded Mongo
Spring Boot offers auto-configuration for Embedded Mongo. To use it in
your Spring Boot application, add a dependency on
de.flapdoodle.embed:de.flapdoodle.embed.mongo and set the
spring.mongodb.embedded.version property to match the version of
MongoDB that your application will use in production. The default
download configuration allows access to most of the versions listed in
Embedded Mongo’s Version class as well as some others. Configuring an
inaccessible version will result in an error when attempting to
download the server. Such an error can be corrected by defining an
appropriately configured DownloadConfigBuilderCustomizer bean.
The port that Mongo listens on can be configured by setting the
spring.data.mongodb.port property. To use a randomly allocated free
port, use a value of 0. The MongoClient created by
MongoAutoConfiguration is automatically configured to use the randomly
allocated port. If you do not configure a custom port, the embedded
support uses a random port (rather than 27017) by default.
If you have SLF4J on the classpath, the output produced by Mongo is
automatically routed to a logger named
org.springframework.boot.autoconfigure.mongo.embedded.EmbeddedMongo.
You can declare your own IMongodConfig and IRuntimeConfig beans to
take control of the Mongo instance’s configuration and logging
routing. The download configuration can be customized by declaring a
DownloadConfigBuilderCustomizer bean.
因此，如果您希望它仅应用于测试，请在 scope:test 中添加以下依赖项。
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
您还需要在 application.properties 文件中设置版本：
spring.mongodb.embedded.version=4.0.21

感谢您的回答。
我试过了，但是好像版本不兼容：
这是我的application.properties
server.port=8085
spring.data.mongodb.uri=${MONGO_URI}
logging.level.root=INFO
spring.servlet.multipart.max-file-size=20MB
spring.servlet.multipart.max-requestsize=20MB

这里我在 pom 中添加了 flapdoodle

src/test/resources/application.属性
spring.data.mongodb.database=test
spring.data.mongodb.port=27017
spring.mongodb.embedded.version=4.0.2
感谢您的回答。
我试过了，但是好像版本不兼容：
这是我的application.properties
server.port=8085
spring.data.mongodb.uri=${MONGO_URI}
logging.level.root=INFO
spring.servlet.multipart.max-file-size=20MB
spring.servlet.multipart.max-requestsize=20MB
server.error.include-message=always
spring.mongodb.embedded.version=4.0.21
这里我在 pom 中添加了 flapdoodle
...
<artifactId>everit-json-schema</artifactId>
<version>1.14.0</version>
</dependency>
<dependency>
<groupId>de.flapdoodle.embed</groupId>
<artifactId>de.flapdoodle.embed.mongo</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
但是如果我开始单元测试，就会出现很多 class 加载程序错误
